dbzz屋頂通風(fēng)機(jī)主要作為石油、化工、紡織、冶金和機(jī)械廠房、辦公室、試驗(yàn)室、倉(cāng)庫(kù)等建筑物室內(nèi)通風(fēng)換氣，它能適應(yīng)建筑物的不同結(jié)構(gòu)形式和使用需要，可安裝在屋頂和墻壁上，當(dāng)工作介質(zhì)溫度為25℃，相對(duì)濕度不應(yīng)大于90%，介質(zhì)含塵量（含固體、雜質(zhì)）應(yīng)不超過1 00mg/m3。
該風(fēng)機(jī)主要由葉輪、風(fēng)筒、風(fēng)帽，電動(dòng)機(jī)及其它附件組成。葉輪采用軸流風(fēng)葉或離心風(fēng)葉，特殊需要可反風(fēng)。風(fēng)帽及底座采用質(zhì)輕、高強(qiáng)度、耐腐蝕的玻璃鋼材料，具有外形美觀、抗風(fēng)雨的特點(diǎn)。
屋頂風(fēng)機(jī)分為WT35(DWT-I)軸流式和WT4-72(DWT-II)離心式兩種。
Performance induction
WT35(DWT-I)、WT4-72(DWT-II) series roof extraction fans are mainly used for ventilation and air-changing inside buildings such as petroleum, chemical, textile, metallurgy, mechanical factory houses, office, experimental room, warehouse, etc. The fan can adapt to different version and needs. It can be installed on the roof or on wall. When the temperature of medium is 25℃, the relative humidity should not greater than 90% , and the dust and hard particles contained should not exceed100mg/m3.
The fan consists of impeller,hair dryer,cap ,motor and other accessories. The impeller takes axial flow fan blade or centrifugal fan blade ,when on special occasion it can be inverted for ventilation. The material used in cap and foundation is glass fiber reinforced plastic materials which is light, high strength and corrosion resistant.The features of cap and foundation are nice appearance and wind resistance.
Roof extraction fans have be divided into two kinds: WT35(DWT-I) axial flow fans and WT4-72(DWT-II) centrifugal fans.
